I got this very cute cake pan at Williams-Sonoma. It looks like a giant Oreo. The pan is actually two pans--A top and a bottom. When they are done they come out of the pan very easily. After it cools, you put them together with the filling. On mine I always make the "cake" part with a boxed brownie mix. I make the filling out of vanilla ice cream. Hmmmmm. The pans do come with a recipe, but nothing beats brownie and ice-cream in my book! Each time I have made this and taken it places, everyone asks me where I got the "giant Oreo pan". And just in case you are wondering...the brownie and ice cream disappear long before the ice cream begins to melt!
